To all whom it may concern:

Be it known that I, IRvIN ROSENFELD, a citizen of the United States, residing at New York city, Bronx, county and Stateof New York, have invented new and useful 1mprovem'ents in Change-Making Machines, of which the followingis a specification.

This invention relates to achange-making machine which will deliver, up to a dollar,

the correct change between the purchase price and the amount received.

The construction of the machine is simple and its operation reliable, so that mistakes in making change are effectively prevented.

In the accompanying drawings Figure 1 is a front elevation, partly broken away, of my improved change-making machine; Fig. 2 a vertical section on line 2--2, Fig. 1; Fig. 3 a plan of the coin magazines and levers; Fig. 4 a detail of the coin-releasing slide;

Fig 5 a cross section on "line 5-5, Fig. 4;

Fig. 6 a detail of one of the coin magazine-s; Fig. 7 a similar detail showing the parts in a 'diilerent position; Fig. a section on line 9 a rear view of the slotted disk; Fig. 10 a 8-8, Fig. 6, with the coins removed; Fig.

. side view thereof, and Fig. l]. a detail showing the engagement'oi said disk with the coin controlling levers.

The frame 20 of the machine is provided with a suitable number of coin magazines each adapted for the reception of a stack of coins. As shown live magazines 21, 22, 23, 24 and-lien areemploycd that contain respectively ,pcnnies 26, dimes 27, nickcls 28, quarteiis illand half dollars 30. The magazines are open at their better and the stacks of coins are normally supported by a series of lugs or coin rests 31, integral with a hori zontally movable spririg-influenced slide 32. This slide may be advanced by its handle to withdraw supports 31 simultaneously from all the magazines, while uponthe release of the handle the slide is returned to its normal position by its spring 33. The reduced sections of the slide between lugs 31 are bevclcd I dial 38 having a corresponding. peripheral scale 39 opposite scale 37. Disk 35 is adapted to actuate, in'manner hereinafter described, a series of elbow levers 40, 41, 42, 43 and 44, fulcrumed on a common arbor 45 and provided on their rear arms with plates 46 beneath the several coin magazines 21--*25. Plates 46 are slotted as at 47 to straddle projections 31 of slide 32 and thus reach the bottom coins of the several stacks, against which they are held by the lower lever-arms weighted'as at 48. Disk 35 is provided on its back with a series of recesses or slots, arranged in concentric zones the number of such zones corresponding to the number of coinlevers 4044.

-Lover 40, controlling the discharge of coin from the penny magazine 21,'is provided with afoot 49 having five steps. These steps ext-0nd transversely across thefirst or outer zone 50 of disk 35, said zone bein divided into; twenty parts, each containing ve steps. Ilt disk 35 is so set that its first step 50" becomes alined with foot49 of lever 40, thelatter locked against movement, as its step 49 will encounter step 50. By turning the disk through one division of scale 37 and thereby bringing step 5O opposite foot 49, the'support for step 49* is withdrawn, so that the lever may be tilted until step 49 engages step 50 This tilting of the lever will, upon the withdrawal of slide 32, be effected by the weight of the coin stack in magazine 21, so that late 46 together with the stack will -be owered a distance equal to the thickness of a single coin. In this way the bottom coin will be lowered to clear magazine 21 and permit its expulsion therefrom by slide 32. If disk is so turned. that step 50 becomes alined with foot 49, the latter will tilt until checked by step 49 so that two coins will be 'released.' In like manner a co-action of steps 50*, 49 will release three coins, while the co-action of steps 50, 49 will release four coins.

Concentric to outer zone 50, disk 35 is provided with four inner zones 51, 52, 53, 54 adapted to actuate levers 41, 42, 43, 44 respectively. Foot 55 of lever 41 is provided with three steps, while the slots of the corresponding second zone 51 are composed of a narrow section 51 merginginto a wider section 51*. When the parts are so ositioncd that slot-section 51 becomes ained with step 55, a single dime will be released from magazine 22, while, when slotsection 51 becomes alined with step 55 two dirnes will be released. The slots of the third zone I I 52 are of uniform width and are adapted to zone 53, co-acting with foot 57 of lever '43,

' so that a five cent piece is discharged.

' respectively discharged.

are adapted to release single quarters from magazine 24, While the slots of the innermost zone 54, co-acting with foot 58 of lever 44, are adapted to release single half-dollars from magazine 25.

As has been stated, zone is divided into 20 sections, each having five steps, thus making one hundred steps in all. The relative arrangement of the slots in disk 35 is such that those slots which are radially alinedwith any one step, release such coin levers as will deliver one cent more in change than the levers released by the slots alined with the preceding step. Thus, when disk 35 is so turned that step 50 on line 1, becomes alined with the coin-levers, the pennylever 4.0 will tilt for the distance of a single ste while none of the other levers LL-42 wil be moved, the disk 35 being imperforate between its steps 50 and its center. In this way but a single cent will be discharged. If disk 35 is so moved as to carry the succeeding steps 50", 50 or 50 opposite the coin -levers, two, three or four cents will be If step 50 on line 2, is brought opposite the coin-levers, the penny-lever 40, as well as the levers 41, 43, 44 will encounter solid sections of the disk, the nickel lever 42 only entering its slot 52, With the osition shown in Fig. 11, there will be discharged four pennies, two dimes and one uarter, because a step 50 a wide dime s ot-section 51 and a quarter slot 53, are brought in alinement wlth the coin-levers,

he machine may be so operated that either the mentall calculated change is delivered by it, or t at it will itself calculate and deliver the correct change. In the first case, disk 35 is turned until the figure on scale 37 corresponding to the amount of change desired 1s brought opposite the zero mark of scale 39. In this position the proper slots of disk 35 become alined with their coin-levers, so that these levers will become unlocked. By now advancing slide- 32, pro s 3.1 are withdrawn from all the coin stac s, so that the latter become supported upon plates 46 only. Thus thereoin stacks on the liberated levers will cause thenlatte n to tilt and thereby lower such coins, as will aggregate the change desired out of the magazines. Slide 32 being next retracted, lugs 3i'will sweep the ex osed coins off plates 46 and into the delivery chiite 34,

- while the lugs 31 will be again returned bei neath the coins remaining in the magazines. The tilted coin-levers becoming thus unburdened, will return to their normal iosition by counterweights 48, ready for the next manipulation. The operation is precisely the same when the machine-itself is to calculate the amount of change. In that case the figure on scale 37 corresponding to the value figure on scale 39 which corresponds to the purchase price, so that in this way the subtraction between the coin received and the purchase price is mechanically performed.

It will be seen that my machine is of simple construction and that all par-ts cooperate in such a manner that the exactchange required is released, so thatwrcliance may be placed on its correctness.
